McKay has enjoyed a wonderful season for the Scottish Championship side.
Barry Ferguson has named Barrie McKay as the player whose place in the Rangers side is secure for next season regardless of the business that Mark Warburton does in the transfer market, the Daily Record reports.
The Gers are preparing for their first season back in the Scottish Premiership. And while the side ran away with the title in the second tier and are one game away from clinching a treble, Ferguson believes that Warburton wants to bring several new faces to Ibrox in the summer, but insisted that the young winger is one of the players that does not need to worry about his place.
"I know Mark Warburton wants to bring in about six players who will go straight into the first team," he told the Record.
"But Barrie's place will be secure because he's made himself one of the first names on the teamsheet."
The 21-year-old's emergence has been one of the brightest aspects of what has been a sensational season for the Light Blues. Though McKay made his debut four years ago, he went into this campaign off the back of two loan spells which suggested that he may be down the pecking order.
But Warburton has made him one of the focal points of the side since his arrival in the summer. Only four players in the Rangers squad have made more appearances than the winger in the Scottish Championship this term.
As well as his six league goals, he has also contributed eight assists which puts him behind only James Tavernier in terms of being the most productive player in that department.
And with his stunning strike at Hampden Park helping the Gers overcome their Old Firm rivals in the Scottish Cup semi-final, he proved that he is more than capable of raising his game on the big stage which will undoubtedly be one of the reasons why Ferguson is backing him to still be a key man for the team once they return to the highest level.
